Ключ (email)=(macmusonda@gmail.com) уже существует ошибка в django

Я пытаюсь зарегистрировать новых пользователей в моем веб-приложении django ecommerce. Я использую пользовательскую модель. Но всякий раз, когда я отправляю форму, моя база данных показывает, что пользователь был сохранен, но затем возникает ошибка "duplicate key value violates unique constraint "account_account_email_key"". ПОДРОБНАЯ ИНФОРМАЦИЯ: Ключ (email)=(macmusonda@gmail.com) уже существует." все еще появляется. Пользователь даже может войти в систему... Как мне избавиться от этой ошибки?

Мой views.py

import email
from django.shortcuts import render, redirect
from django.contrib.auth import login, authenticate
from account.forms import RegistrationForm
from django.contrib import messages
from .models import Account



def registration(request):
    if request.method == "POST":
        form = RegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            first_name = request.POST['first_name']
            other_names =  request.POST['other_names']
            email =  request.POST['email']
            username = request.POST['username']
            raw_password =  request.POST['password1']
            phonenumber =  request.POST.get('phonenumber')
            Address_1 =  request.POST['Address_1']
            Address_2 =  request.POST['Address_2']
            user = Account.objects.create_user(first_name=first_name, other_names=other_names, email=email, username=username, password=raw_password, phonenumber=phonenumber, Address_1=Address_1, Address_2=Address_2)
            user.save()
            messages.success(request, ('Your account was successfully created!'))
            login(request, user)
            return redirect('home')
        else:
            messages.error(request, ('Invalid input.'))
    else:
        form = RegistrationForm()
    return render(request, 'account/register.html', {'form': form})

def login(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(request, username=username, password=password)

        try:
            user = Account.objects.get(username=username)
        except:
            messages.error(request, 'username does not exist')

        user = authenticate(request, username=username, password=password)

        if user is not None:
            login(request, user)
            return redirect('home')
        else:
            messages.error(request, 'Invalid Username Or Password')
    return render(request, 'account/login.html')

И мой models.py

import email
from django.db import models
from django.conf import settings
from phonenumber_field.modelfields import PhoneNumberField

from django.contrib.auth.models import AbstractBaseUser

        if not email:
            raise ValueError("User must have an email")
        if not username:
            raise ValueError("User must have a username")

        user = self.model(
               email = self.normalize_email(email),
               username = username, password=password, first_name = first_name, other_names = other_names,
               phonenumber = phonenumber, Address_1 = Address_1, Address_2 = Address_2
            )   

        user.set_password(password)
        user.save(using=self._db)
        return user 

    def create_user(self, email, username, password, first_name=None, other_names=None, phonenumber=None, Address_1=None, Address_2=None):
        return self._create_user(email, username, password,first_name, other_names, phonenumber, Address_1, Address_2)

    def create_superuser(self, email, username, password):
        """

        user = self.create_user(email=email,
            username=username,
            password=password,
            
        )
        user.is_admin = True
        user.is_superuser = True
        user.is_staff = True
        user.save(using=self._db)
        return user


class Account(AbstractBaseUser, PermissionsMixin):
    first_name = models.CharField(verbose_name='first_name', max_length=60, null=True)
    other_names = models.CharField(verbose_name='other_names', max_length=200, null=True)

    Address_1 = models.CharField(max_length=60, blank=False, null=True)
    Address_2 = models.CharField(max_length=60, blank=False, null=True)
    date_joined = models.DateTimeField(verbose_name='date_joined', auto_now_add=True)
    last_login = models.DateTimeField(verbose_name='last_login', auto_now=True)
    is_admin = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']
    objects = MyAccountManager()


    def __str__(self):
        return self.username

    def has_perm(self, perm, obj=None):
        return self.is_admin

    def has_module_perms(self, app_label):
        return True

Я действительно не знаю, как справиться с этой ошибкой... нужно объяснение, откуда она берется и как от нее избавиться
